We are using Terminal Services for our viewer users to connect to our EPDM Vault, so there could be a couple of people accessing files at the same time. The users use the windows explorer embedded eDrawings for measuring dimensions and occasionally printing drawing copies.

Under these circumstances, if I can view a drawing one day on the viewing server. Then make some changes using a CAD machine, however the original drawing is still stored on the viewing client. If i view that drawing again, there is an icon under version that states "You do not have the latest version of this file on your local hard disk." I can easily view/print the old version using eDrawings if i miss that icon. The only way to get the latest would be to do this manually.

Is it possible to be 100% confident that, when viewed through Windows Explorer eDrawings, the file is the latest version?

This is quite possible and it's just a small checkbox you have enable.

Right mouse click on the group of viewers you want them to always refer the latest versions of files, Go to settings, Click on Explorer Tab and under misecellaneous heading Enable the "Always work with the Latest verions of file"

By enabling this option system always forces the user to work with the latest version.
